John Dyson 5856e12e69 Fully implement vfork. Vfork is now much much faster than even our ... fork. (On my machine, fork is about 240usecs, vfork is 78usecs.) Implement rfork(!RFPROC !RFMEM), which allows a thread to divorce its memory from the other threads of a group. Implement rfork(!RFPROC RFCFDG), which closes all file descriptors, eliminating possible existing shares with other threads/processes. Implement rfork(!RFPROC RFFDG), which divorces the file descriptors for a thread from the rest of the group. Fix the case where a thread does an exec. It is almost nonsense for a thread to modify the other threads address space by an exec, so we now automatically divorce the address space before modifying it.		1997-04-13 01:48:35 +00:00
